The object of my invention is to provide 2. rotor, the parts of which will be to menufslcture end to assemble, and wlueh will be strong, durable, and eompect zm(l l elm up the? to improve, in general. the design 1.. such members.

1 pro ide at each side the spider of the rotor and preferably in tegrsl therewith, fen blades, and mount on the outer surface of these bled es short-eircuitingg rings for the con duster-bars.

My invention consists incertein novel ztrrengeiments of parts and combinations of elements more clearly described in the speci- "licetion and definitely set forth in the ep" pended claims. v

For it better understanding of my invention, reference is hscl to the accompanying drawing, in WlliCl'l,

Figure 1 is a side elevation of my improved rotor, parts being in section for the sake of cleerness; and Fig. 2 is end. view of same.

I have shown at 10, the shaft upon which the spider of the rotor is mounted. der' consists of a hub 11., redial arms 11? and. an outer rim 1 3 which supports the laminate-(l core 14. The laminae of the core ere secured to the rim in any desired m armor and are held between end-plates 15 and 15 the former of whlch 1s mtegrel xth the frame.

The lemi- 11% and plate 15 are held in place by split holding ring 16. The core is provided with the usxiel slots for receiving the conductorbars 17, which, together withv the short cireuiting rings 18, form a squirrel-cage W 1nd.- ing.
